Stewart Brand: The dawn of de-extinction

Throughout humankind's history, we've driven species after species extinct: the passenger pigeon, the Eastern mountain lion, the dodo .... But now, says Stewart Brand, we have the technology (and the biology) to bring back species that humanity wiped out. So -- should we? Which ones? He asks a big question whose answer is closer than you may think.

Passenger pigeons went from 5 billion to zero in twenty years



Using George Church's synthetic biology we can take the nearest genetic relatives DNA and synthetically evolve it to the desired genome sequence






There will also need to be a strategy to re-establish each of the species that are brought back in their old breeding grounds.
